Aegires punctilucens from Sydney

From: Bill Rudman

To accompany my discussion [message #14248] on Aegires punctilucens and A. exeches here are some photos of an animal from Sydney I have posted a photo of it before [message #9052] but these show some of the details more clearly.

Locality: Green Point, Sydney Harbour, NSW, Australia, c 9 m. 10 June 1978. AM C110117. Photo: R & A Kuiter .

It has a symmetrical arrangement of the tubercles and the colour pattern is clearly visible in the spaces between the tubercles. In the lower right photo showing the rhinophore the bifid tip is visible. Also visible in this close-up are small opaque whitish granules which I suspect are the white specks illustrated by d'Orbigny.

Of particular interest are the shape of the tubercles. Most are rounded at the tip but a few are flattened. Look at the bottom right tubercle in lower left photo, and at the tubercle closest to the viewer on the rhinophore sheath in the lower right photo. The tubercles can change shape within a few minutes, and similarly sometimes protruding spicules are quite obvious and at other times there is no sign of their presence.
